This vocabulary describes parameters common in audio processing software. A parameter is purely a metadata concept, unrelated to any particular code mechanism. Parameters are used to assign meaning to controls (e.g. using lv2:designation for ports) so they can be used more intelligently or presented to the user more efficiently.
A group representing a set of associated controls.
The duration of an envelope's attack stage.
The duration of an envelope's decay stage.
The duration of an envelope's delay stage.
The duration of an envelope's hold stage.
The width of a pulse of a rectangular waveform.
The duration of an envelope's release stage.
The level (not duration) of an envelope's sustain stage.
The ratio between processed and bypass components in output signal. The dry and wet percentages can be calculated from the following equations: dry = (wetDryRatio.maximum - wetDryRatio.value) / wetDryRatio.maximum wet = wetDryRatio.value / wetDryRatio.maximum Typically, maximum value of 1 or 100 and minimum value of 0 should be used.
The level of the processed component of a signal.
The level of the unprocessed component of a signal.
A boolean parameter that disabled processing if true.
